Design a Western Blot for WNT16

Band shift · Use the separately labelled calculated mass and catalog-observed evidence above. A sequence annotation does not establish an observed migration shift. Verify target identity with orthogonal controls.

Isoforms · Two isoforms are listed: Wnt-16b and Wnt-16a. Wnt-16a has an alternative sequence at UniProt residues 1–32. Check which isoform the sample and antibody cover before assigning bands; the supplied features do not establish their apparent sizes.

PTM · UniProt lists N-linked sites at Asn143, Asn189, and Asn311. These are coordinates in the supplied UniProt sequence; check the numbering convention before comparing them with an antibody or paper. The site annotations alone do not prove a visible shift.

Induction · No general induction response is established by this guide. A pathway or gene-set association is not evidence of induction in a particular specimen. Verify the relevant treatment and control in a target-specific experiment.

Transfer · Standard workflow guidance: verify transfer efficiency for the intended target size before interpreting a weak signal. Use total-protein assessment and optimize transfer for the membrane, gel and apparatus; the labelled catalog values take precedence.

Blocking · Standard workflow guidance: follow the A03606-1 datasheet where specified. Otherwise compare 5% milk or 5% BSA in TBST; for a phospho-specific assay start with BSA. Optimize background and specific signal with matched controls.

Quantitation · Standard workflow guidance: quantify only a validated target band within the linear exposure range. Use consistent sample preparation and loading, retain biological replicates, and avoid interpreting saturation or loading differences as regulation.

Interpretation · The 40.7 kDa value is predicted. WNT16 has a signal peptide at residues 1–29 and three listed N-linked glycosylation sites. These features may affect the protein detected, but they do not establish an apparent band size or explain a particular mass difference.

UniProt annotates a signal peptide at residues 1–29 of the supplied sequence. Consider signal peptide processing when comparing a band with the 40.7 kDa predicted value, but do not assign a processed band size from this annotation alone. Wnt-16a has an alternative N-terminal sequence, so check isoform numbering.

WNT16 is annotated as secreted and located in the extracellular space and extracellular matrix. Consider those compartments when choosing samples and interpreting a weak signal in a cell lysate.

Use the same sample compartment across comparisons, since WNT16 is annotated in the extracellular space and extracellular matrix. Define which bands you quantify consistently; two isoforms and three N-linked glycosylation sites are listed, but their apparent band patterns are not supplied.

Check whether the bands are consistent with the two listed isoforms, the alternative N-terminal sequence, signal peptide processing, or the three annotated N-linked sites. The features do not identify any particular observed band, so they cannot confirm its identity or explain its size on their own.
